It works "pretty well" with U-boot built for sheevaplug - my main problem now is that it hangs on miiphy_reset.
I can confirm that. Have the same behaviour but haven't time to investigate further. Maybe we can share information and coordinate some work?
Sure. I've created a board support package for OpenRD base which is still basically a copy of sheevaplug. I can submit it if Prafulla wants to, but it's very preliminary still.
Simon, could you please post it on the list, or if this is uncommon send it per mail to me?
Thanks in advance, Dieter
The problem with the phy_reset was simple though: The phy simply has a different address than the one for sheevaplug. The patch below (against my board package - not possible to apply!) fixes this.
